Abstract
The final targets are established by different types of functional groups on aryl azides with terminal alkynes of pefloxacin via click chemistry in conventional and microwave irradiation conditions. A series of novel derivatives are characterized by proton, carbon nuclear magnetic resonance technique and mass spectral techniques. From screening antibacterial results the 5c, 5d, 5e, 5f and 5g exhibited outstanding activity against Gram-positive and Gram-negative microorganisms compared to CPF. All the title compounds were subjected to molecular docking prediction and compounds 5h, 5a, 5g possesses the highest binding energy ΔG= –8.12, –7.61, –7.26 Kcal/mol, hydrogen bonding amino acid interactions Val40, Asp83, Lys93, Tyr23, Arg28 with the active site of Topoisomerase-IV from S. pneumoniae (4KPE). Further investigation, these compounds were evaluated to their molecular properties prediction by Molinspiration and Molsoft
